Cigarette smoking is a significant contributor to global warming!

Each and every one of us can make changes in the way we live our lives and become part of the solution [to climate change]

I'm a big fan of Bitcoin ... Regulation of money supply needs to be depoliticized.

I just think that a much more important part of the problem we face, which was evident 10 years ago and is even more evident now, is that the way we share information among ourselves as American citizens has been radically transformed. The line between news and entertainment has almost dissolved, where ratings now have a big impact on what kinds of stories are covered and not stories.

The American people overwhelmingly want our troops out of Iraq. They want the federal government to take real and immediate action to combat global warming and to significantly expand support for stem cell research. Democrats almost unanimously support the people's wishes onthese crucial issues. Republicans don't.

John McCain is now openly endorsing the policies of the Bush-Cheney White House and promising to actually continue the same policies over again? Hey, I believe in recycling but that's ridiculous.

...the emergent capabilities bursting forth from the revolutionary advances in the life sciences are about to make us the principal agent of evolution.
